To increase the capacity of a LoRaWAN network, several strategies can be employed: 1) Optimize Data Rates and Spreading Factors (SF) LoraWAN uses different spreading factors (SF7 to SF12), with higher SF values increasing transmission range but lowering data rates. By optimizing the adaptive data rate (ADR), the network can assign lower SF values to devices closer to gateways, reducing transmission time and increasing overall network capacity. Devices further away can use higher SF values, benefiting from the longer range. 2) Increase Gateway Density Deploying more gateways in strategic locations can significantly increase the network capacity. More gateways mean more frequency channels and higher chances of devices communicating without collisions.… \u7d9a\u304d\u3092\u8aad\u3080 \u00bbLoRaWAN \u30cd\u30c3\u30c8\u30ef\u30fc\u30af\u306e\u5bb9\u91cf\u3092\u5897\u3084\u3059\u306b\u306f\u3069\u3046\u3059\u308c\u3070\u3044\u3044\u3067\u3059\u304b?<\/span><\/a><\/p>","protected":false},"author":1,"featured_media":17995,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"","neve_meta_content_width":0,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":"","footnotes":""},"categories":[268],"tags":[],"class_list":["post-17984","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-iot-faqs"],"_links":{"self":[{"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/posts\/17984","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/comments?post=17984"}],"version-history":[{"count":0,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/posts\/17984\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/media\/17995"}],"wp:attachment":[{"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/media?parent=17984"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/categories?post=17984"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/tags?post=17984"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
